Description
Technical field
The present invention relates generally to the luminaire of the light that can produce varying strength.Especially, the present invention relates to a kind of so-called Wake-up Light, or on the contrary, so-called sleeping lamp.
Background technology
Wake-up Light is a kind of like this lamp; It comprises one or more light sources; The power of light source (corresponding to light intensity) is in the certain hour section, and for example (or near zero initial value) is increased to maximum lentamente and little by little from zero within 30 minutes, and holding power after this.Such lamp is used to simulate the natural process that in sunrise, increases day lighting level, and this has positive impact to waking the people up.This process also can be moved conversely; Thereby make power (corresponding to light intensity) reduce to zero (perhaps near zero end value) from maximum lentamente and little by little; With the natural process of simulation minimizing day lighting level in sunset, this falls asleep for the people has positive impact.
Wake-up Light and sleeping lamp are known, therefore omit more detailed explanation at this.In addition, for easy, following explanation will concentrate on Wake-up Light, but the in addition necessary then same explanation of change is applicable to sleeping lamp, and this point should be clearly to those skilled in the art.
Wake-up Light can adopt dissimilar light sources and realize.For example, the light source of use can be electric filament lamp, discharge lamp, LED etc.The output that changes light source is realized through changing lamp current usually.
Summary of the invention
A key property of the light that light source produced is its color.Typically, photochromicly can depend on lamp current.For example, under the situation of electric filament lamp, light color is that red-hot redness arrives orange (corresponding to low relatively filament temperature) when hanging down lamp current, and light color is yellow to white (corresponding to high relatively filament temperature) when high lamp current.So, this is an active influence, because it is roughly corresponding to the change in color of daylight at sunrise (and, on the contrary, sunset).On the other hand, also exist constant color, with the irrelevant light source of lamp current.
Hereinafter, light intensity slow said time period that increases or reduce during it will be indicated as being wake-up period or sleeping cycle respectively.In addition, the light intensity of output will be indicated as being steady statue intensity after accomplishing wake-up period, corresponding to steady state current.Usually, steady state current equals to be the maximum of the light source design of being paid close attention to or rated current, and therefore steady statue intensity equals maximum or normal light intensity.The objective of the invention is to provides the level of setting steady statue intensity other probability for the user.
This purpose can easily realize through only lamp current being limited to certain rank.Yet thing followed problem is the photochromic brilliant white that is associated with whole completion wake-up periods usually that is different from corresponding to the steady state current that reduces like this.This is shown among Fig. 1.
In the chart of on the left side, curve 1 shows lamp current or the light intensity (longitudinal axis, arbitrary unit) as the function of time (transverse axis, minute), its in 30 minutes wake-up period from 300 the maximum that is raised to above freezing.Related color change is indicated by curve 2.Really, be difficult in this chart the color visualization, but supposition, for color, longitudinal axis representative line from red to white in color chart.In addition, in order to explain, suppose along the position of such color line directly to be proportional to light intensity.
The chart on the right shows such position, and the user is made as 100 with steady statue intensity here, and perhaps 33% of maximum (curve 1 '), and wake-up period maintains 30 minutes (though this and non-essential).Curve 2 ' show light intensity only is restricted to the related color change of specified 100% 33% simple realization.Should be able to easily understand, when wake-up period finishes, realize photochromic be corresponding to colo(u)r streak 33% photochromic.In other words, be different from photochromic (horizontal component of curve 2) during steady statue under 100% situation at photochromic (curve 2 ' horizontal component) during the steady statue.
The object of the present invention is to provide solution for this problem.
According to an important aspect of the present invention, during wake-up period, the color of output light is independent of temporal light intensity and controlled, with the change color of simulation sunrise, and when wake-up period finishes resulting photochromic be fixed, be independent of steady statue intensity.In a preferred embodiment, the user also can set this steady statue color.
Favourable being set forth in the independent claims in addition mentioned.
Effect visualization of the present invention is in the chart of the right of Fig. 2, and the left side is identical with Fig. 1 with intermediary figure with relatively convenient.Curve 1 " with curve 1 ' identical: light intensity little by little rise to specified 100% 33%." identical with curve 2: the color path that the color dot in color space is passed through is identical with the color path of under specified 100% situation, being passed through to curve 2.
Notice that US7280439 has disclosed a kind of illuminator that influences change color with simulation sunrise.Yet this document is not disclosed in the adjustable maximum of user of the light intensity during the steady statue, does not disclose the result of cColor-cycling yet.
US2004/0264193 discloses the control of LED substantially, so that the control colour temperature.
US-5327331 has disclosed a kind of like this Wake-up Light, and wherein colour temperature is kept constantly, and light output intensity increases.
Description of drawings
Below will be with reference to accompanying drawing, further explain these and other aspect of the present invention, characteristic and advantage through the description of following one or more preferred embodiments, the identical identical or similar part of Reference numeral indication in the accompanying drawing, and wherein:
Fig. 1 shows for the light intensity of different situations and photochromic graph of function table as the time;
Fig. 2 shows light intensity and photochromic function as the time so that chart of the present invention to be described;
Fig. 3 is the block diagram that schematically illustrates according to the exemplary embodiment of luminaire of the present invention;
Fig. 4 schematically illustrates color chart.
The specific embodiment
Fig. 3 is the block diagram that schematically illustrates according to the possible embodiment of luminaire 100 of the present invention.Luminaire 100 comprises at least one controllable light source 110, is used to control the control appliance 120 of light source 110, the first memory 130 that is associated with control appliance 120, and the second memory 140 that is associated with control appliance 120.Control appliance 120 can for example be implemented as the microcontroller of programming suitably, and it is that light source 110 produces control signal, thereby causes that light source 110 produces the light with certain desired color and certain expectation strength.
Through the mode of indefiniteness example, light source 110 comprises three (or more) LED (or light producing component of other types) 111,112,113, and each generation has the light of the unicolor color of diacritic ideal, and these colors differ from one another.For example, these colors can be red (R), green (G), blue (B).As those skilled in the art should know that the integral light output of light source 110 is mixing of these three light outputs, the light output that the human eye perception should integral body is mixed into has blend color, this blend color depends on the mutual ratio of three kinds of light contributions.
Although it will be appreciated by those skilled in the art that the brief overview of color theory will provide below.
Color can be represented by three parameters independent of each other; Can be with reference to CIE1931 (XYZ) system, wherein X, Y, Z have been expressed as and have obtained the needed intensity with color of special definition of particular color, and the color of special definition for example is respectively red 700nm, green 546.1nm and blue 435.8nm.Here, " color " means the combination of colourity and lightness.In CIE1931 (XYZ) system, the variation of one of X, Y or Z value will cause the variation of the combination of colourity and lightness.Can be out of shape coordinate system, wherein colourity and lightness are independently of one another.Such system is for example for having CIE (xyY) system of coordinate x, y, Y, and wherein x and y are chromaticity coordinates and capitalize Y and indicate brightness.Distortion about color coordinates is defined by following formula:
These formula still show three variable x, y, z, but z is redundant variable (being non-independent variable), because z can be calculated by x and y according to following formula:
z＝1-x-y (1d)
Therefore, the colourity of all colours can be shown in the xy plane of two dimension, and as shown in Figure 4, it has schematically shown CIE (xy) chromaticity diagram.This figure is known, therefore only does the most concise and to the point explanation.Point (1,0), (0,0) and (0,1) are indicated ideal red, blue and green respectively, and they are virtual colors.Curve 41 expression pure spectral color.Wavelength is that unit illustrates with nanometer (nm).The end points of dotted line 42 junction curves 41.The zone 43 that is fenced up by curve 41 and dotted line 42 comprises all visible color; Than the pure spectral color of curve 41, the color in zone 43 is blend colors, and it can obtain through mixing two or more pure spectral color.Conversely, each visible color can be represented by the coordinate in the chromaticity diagram; Naming a person for a particular job in the chromaticity diagram is indicated as " color dot ".
Replace for example being expressed as " the brightness Y " of absolute value of the pilot light of lumen, use " lightness B " traditionally in light source field, it is a relative parameter.(x y), exists maximum can obtain brightness Y for each color dot
MAX(x, y), when intrinsic brilliance Y has value L, lightness is defined as
B＝L/Y
MAX (2)
Like this, lightness is the value between 0 to 1.
In addition, replace color coordinates x, y, also possibly use the color harmony saturation.With reference to figure 4, (x y) obtains in the color space the most easily explaining the basic conception of tone, saturation and lightness, although can access other definition at other color spaces at CIE1931.For simply, hereinafter use CIE1931 (x, y) color space.
When two pure spectral color mixing, the color dot of final mixed color is positioned on the line of the color dot that connects two pure colors, and blending ratio (volume efficiency) is depended in the definite position of final color dot.For example, when purple and red mixing, the mauve color dot of final mixed color is positioned on the dotted line 42.If two colors can be mixed the generation white light, they are called " complementary color ".For example, Fig. 4 shows the line 44 that connects blue (480nm) and yellow (580nm), and this line passes white point, and the correct volume efficiency of indication blue light and gold-tinted will be perceived as white light.Same situation is applicable to the complementary color of any other combination: under the situation of corresponding correct volume efficiency, light mixes will be perceived as white light.Notice that light mixes the spectral contribution that in fact still comprises two different wave lengths.
Notice that many visible color can obtain through mixing two kinds of complementary colors, but this and be not suitable for all colours, like what from Fig. 4, can see easily.Suppose three produce different colours have assembly respectively corresponding to the lamp of separately color dot C1 (being bordering on redness), C2 (being bordering on green), C3 (being bordering on blueness): have such assembly, can be created in by any desired color within these three corresponding color dot C1, C2, the defined triangle of C3.
Increasing under the 4th lamp situation with color dot C4 (being bordering on white), color no longer obtains as the unique combination of three kinds of light output, and can obtain with several kinds of different modes as the combination of four kinds of light outputs.When hope strengthened the for example xanchromatic contribution of certain color, this possibly be particularly useful.
Work as The sun came up, its color changes to white through orange with yellow from redness; At sunset, opposite change color takes place.Curve 45 is to be merely the exemplary path of discussing and providing, the path that the color dot of its solar simulated is passed through.Although the color dot of daylight possibly change because of weather environment, the Actual path of being passed through by the color dot of daylight can be considered to fixing true, and the practitioner can simulate or be similar to the practical path of true path like the selection of expectation.According to the present invention, the definite coordinate in practical path is incoherent.According to the present invention, relevant is that the information that has defined so practical path is stored in the first memory 130.This practicality path will be indicated in the following and is " sunrise approximate path ".
At " shut " mode", light source 110 is closed.
Under stable mode, the control signal that is kept for light source 110 is constant, thereby makes that output light color and output light intensity are constant.
Under awakening mode, control appliance 120 is its control signal of function change that light source 110 is accordinged to the time, the sunrise approximate path from the red end to the white end thereby the photochromic point of feasible output is passed through, and make output light intensity slowly increase.
Under sleeping pattern, be light source 110 change its control signal according to the function of time with control appliance 120, thereby make output photochromic along the opposite direction sunset approximate path of passing through, and promptly from the white end to the red end, and makes output light intensity slowly reduce.In a variant, first memory 130 can be stored two different paths, a sunrise approximate path and a sunset approximate path, and control appliance 120 makes and exports the photochromic sunset approximate path of under sleeping pattern, passing through in this example." color speed " can be constant or can change according to the function of time.
The normal use of luminaire 100 will typically relate to the order that experience is in the morning closed/waken up/stablizes/close, at night the experience order of closing/stablizing/falling asleep/closing.Transformation from the " shut " mode" to the awakening mode can be accomplished waking up on the basis of intervalometer automatically, but this is not shown in the drawings for simple.
It is the output light intensity during stable mode that another user in context of the present invention is provided with, and it will be indicated as the steady statue intensity I
STEADYPreferably, the setting of steady statue intensity also can for example be changed during the awakening mode, but steady statue intensity will be regarded as fixed value hereinafter.Light source 110 possible maximum intensity under stable mode will be indicated as I
MAXRatio I
STEADY/ I
MAXTo be indicated as and stablize lightness β.
Institute during awakening mode is free, and control appliance 120 will produce it and be used for the control signal of light source 110 on the basis of the information in first memory 130 and the second memory 140; Same situation is applicable to sleeping pattern.The control signal that is used for light source 110 is in fact by being used for each LED 111,112,113 and possible additional white each control signal yellow or amber LED is formed.As above-mentioned, first memory 130 comprises and is used for integral body is exported the information that definitions of color is the function of time.This information can for example be the form of question blank; Comprise fixedly installing for the output current of the per time unit of each light producing component; Perhaps for example be the form of formula, allow to according to the function of time and calculate for the output current of each light producing component.Likewise, second memory 140 comprises the information that the development of intensity is defined as the function of time; This intensity can change along with the time linearly, and perhaps parabola ground changes (as shown in Figure 2), the perhaps function of any other expectation.
For time signal is provided, device 100 comprises clockwork 150.The specified persistent period of supposing awakening mode equals 30 minutes (1800 seconds), and control appliance 120 adopts 100 grades: this means that control appliance 120 is with consult memorizer 130,140 per 18 seconds once and adjust it and export signal specifiedly.Suppose that the user has set 30 minutes persistent period of α (a less than or greater than 1): this means control appliance 120 will be in fact every α consult memorizer 130,140 18 seconds once and adjust its output signal.Even without providing more detailed explanation, those skilled in the art know that how can adjust time scale according to the persistent period that the user is provided with.In addition, should know that control appliance 120 can be designed as its control signal of change in discrete level, every a lot of seconds once, but also possibly be designed to change continuously its control signal by control appliance 120.
At all time t, control appliance 120 calculates the respective intensities Ie (t) that each light produces optical element 111,112,113 according to following formula:
Ie(t)＝IM(t)·R(t)·β
Here, the intensity only calculated on the basis of the information in first memory 130 of IM (t) indication.If being combined into maximum intensity, R=1 and β=1, these intensity mixes the output color accurately.It should be noted that IM is the function of time, therefore implement the change of color according to the function of time, perhaps in other words, along the stroke of color path 45.
R (t) indication is by the volume efficiency of deriving in the second memory 140 (0 to 1) as the function of time: this implements the time profile of expectation of the increase/minimizing of intensity.
β indicates like the defined stable lightness in front: this implements maximum setting that the user instructed.
It should be noted that because the intensity of all light producing components all multiplies each other with same factor-beta R (t), the color dot that mixes output light remains identical.Should also be noted that changing intensity keeps the color of indivedual light producing components simultaneously and can be achieved through dutycycle control, clearly like those skilled in the art institute.
In a word, the invention provides to have and wake up and/or the luminaire 100 of sleeping function, comprising:
At least one controllable light source 110;
Be used to control the control appliance 120 of light source 110.
Under stable mode, the color and the intensity of output light are maintained constant at stable color value and stable intensity level.
Under awakening mode, the output light intensity little by little is increased to the strength of stability value from zero; Under sleeping pattern, the output light intensity little by little reduces to zero from the strength of stability value.
Although the present invention has obtained detailed explanation and description in the description of accompanying drawing and front, those skilled in the art will be understood that such explanation and description should be regarded as illustrative or illustrative rather than restrictive.The invention is not restricted to the embodiment that disclosed; On the contrary, within the defined protection scope of the present invention of accompanying Claim book, have various deformation and modification.
For example,, two independent memorizeies are provided like embodiment described above, the function that will be defined as the time along the stroke of color path, another is defined as specified strength development the function of time.And independent memorizer comprises combined information IM (t) R (t) that color and specified strength development are defined as the function of time also is possible.
In addition, among the described in front embodiment, light source 110 comprises a plurality of smooth producing components, and each has fixed color; Under these circumstances, the present invention can be achieved through the relative weighting that the light output that changes these elements is contributed.Yet, also possibly use one (or a plurality of) to produce optical element, each can produce the light of variable color, and its color value can be regulated by control appliance.No matter only comprise a light producing component or two or more, basic relevant issues are that the color output and the intensity of light source 110 can be controlled independently.
In the above-described embodiments, control appliance 120 color dot that is described to control especially output light is with solar simulated effect especially.Yet there also have embodiment need not to be so complicated.For example, possible light source 110 only comprises two light producing components, and element produces white light and another element produces warmer light, and wherein two light producing components are controlled by control appliance 120 independently influences change color to be independent of strength of stability.The first smooth producing component can for example be that the CFL lamp and second light-emitting component can for example be neon lamp (such as being used for night-light or refrigerator).
Through research accompanying drawing, disclosure and the accompanying claims, those skilled in the art can understand when implementing invention required for protection and other variations of the embodiment that realizes being disclosed.In claims, word " comprises " does not get rid of other elements or step, and indefinite article " " is not got rid of a plurality of.Several the function of mentioning in claims can be accomplished in an independent processor or other unit.Some means appears at the combination of not representing these means in the different independent claims can not be by favourable use.Computer program can be stored/be distributed on the suitable media; Provide or as the part of other hardware and the solid media that provides such as optical storage medium or with other hardware; But also can be distributed in other forms, such as via the Internet or other wired or wireless telecommunication systems.Any Reference numeral in claims should not be understood that the limiting protecting scope.
